With a new floor, freshly painted walls and the busy chatter of customers, Cafe Racer re-opened on Friday — seven weeks after a gunman killed four people inside in one of Seattle’s worst mass shootings.

Someone inside an artsy Seattle cafe where a gunman opened fire threw stools at the assailant during a shooting rampage police described as “callous, horrific and cold,” a move that allowed others to run to safety.

A city already anxious about a recent spate of shootings was rattled further when a man walked into an arts cafe near a Seattle university and opened fire, fatally wounding four people on Wednesday. Police say he later killed a woman during a carjacking before shooting himself.

A gunman opened fire at a Seattle cafe on Wednesday, killing two people, critically wounding three others and setting off a manhunt that forced officials to close nearby schools, authorities said. One of those critically wounded has died at Harborview. Police searching for the suspect also had to respond to another fatal shooting near the city’s downtown. They say a man killed a woman in an apparent carjacking and fled in a black SUV into a West Seattle neighborhood.
